Denise said losing her son has left her feeling as though she is serving a life sentence

She told the Mail on Sunday: "There aren’t the words to describe how I still feel now, every day. I was the one who let go of his hand; I was the one there meant to protect him.

"But do you know what my biggest regret is? That I didn’t turn right instead of left – if I had taken the right turn and gone around the corner, I would have seen James being led away, just four short minutes after he had left my side, trustingly holding hands with the boys who were about to murder him."
